Mini-case

«I held a series of consultations for a German startup. We needed a simple way to process a one-off service without long-term contracts. OnePay allowed me, as an individual, to legally issue an invoice. The client paid by card, and I received the money the next day. Ideal for project work».

Elena / marketing consultant

Mini-case

«I travel constantly and work with clients from different countries. OnePay solved my biggest problem—global payments. I especially appreciate the option to withdraw funds in crypto. It’s fast, convenient, and removes the headache of currency conversion. Now I can legally get paid from anywhere».

Alex / digital nomad

Mini-case

«I took an order from a new client and was worried about payment. What convinced me to use OnePay was the payment protection: the rights to my design only transfer after I get paid. This gave confidence to both me and the client. No more working ‘for a thank you’—everything is transparent and backed by documents».

Pavel / graphic designer

Frequently Asked Questions

Do I need to pay a monthly subscription fee?

No. You only pay a 5% commission on successfully paid invoices. If you don’t have projects, you pay nothing.

No, you don’t. You work as an individual through the OnePay platform, which acts as your legal partner (EOR).

Companies and individuals in Poland, the EU, and worldwide (except for sanctioned countries).

For Polish tax residents, we automatically calculate and withhold tax (PIT). All reporting is available in your profile.

When creating an invoice, simply choose whether to “transfer rights” or “grant a license.” Documents are generated automatically.
